A user running the Ella theme (version 6.5.2, unsupported) encountered an issue where all product blocks across pages and collections were shifting horizontally to the right.
Root Cause:
The problem stemmed from CSS code in the component-loading-overlay.css file, specifically within the .media--loading-effect class. This code created a shimmer animation with a linear gradient background that caused the unwanted horizontal movement.
Resolution:
Initially, deleting the first block of problematic CSS code partially fixed the issue, though background movement persisted.
A second loading-related code block in the same CSS file was identified and needed removal.
After removing both code sections, the issue was resolved.
The discussion concluded successfully with the user confirming the fix worked.
